Description
Dahua IPC-HFW2831T-AS-S2 Security Camera
With upgraded H.265 encoding technology, Dahua Lite series network camera has efficient video encoding capacity, which saves bandwidth and storage space. This camera adopts the latest starlight technology and displays a better colour image in the condition of low illumination. It supports SD card storage, dust-proof function, waterproof function and vandal-proof function, complying to the standards of IP67 and IK10 (Supported by some select models).
Through advanced video algorithms, Dahua's Intelligent Video Surveillance (IVS) technology supports smart functions such as tripwire and intrusion detection.
Starlight technology generates clear images in near-complete darkness. A high-performing sensor and special algorithms work together to capture images in low-light and no-light environments.
